webui: dislay server suffixes in server search page
There was a change where suffixes in server are not longer returned as DNs
but rather a cn of related topology suffix. I.e. they share "memberof" logic.
This caused that search page doesn't get the data because it uses
"no_member: true" option by default.
This patch overrides the behavior because it is OK for server search page
to fetch also member data - it is not so costly as e.g. in users.
